Yeah, I have a 5 month old panther as well. I stopped giving him those about a month ago... I figured that they are just to small and not really worth it. If you want to try it, I put them into a cup and would dust them then sprinkle them on the trees/leaves of the cage. Or you can leave them in the cup if your cham cup feeds... once they are dusted, they cant climb up the cup! If you leave them in the cup I would make sure you take them out before misting... just a couple drops of water in the bottom of the cup will drown them! good luck
